  • Question

    How tin I make sure fuel is getting to the motor after changing the filter on my boat?

    Community Answer

    If you have a fuel injected engine, and so after installing the new filter, turn the ignition key to the "on" position (not "start") for a few seconds. Listen for the faint whine of the electric fuel pump building pressure. Plow the key off when you hear the pump finish. Plough the key on over again. If the fuel pump starts VERY briefly, that ways yous have filled the filter and the system has pressurized. If the fuel pump runs longer than a second, repeat the off-on cycle a few more times. If your engine is non fuel injected, then consult a local marine mechanic - priming fuel systems on carbureated boat engines is beyond the telescopic of online DIY communication.
